Title: Dam for shield terminators
Inventor: SPECTOR ROBERT J
IPC: H01R4/64
Filed: 1990-01-03
Abstract: F.N. 43535 CAN 1A                  Abstract of the Disclosure A shield terminator for sealing the splice of a ground lead wire and the shield of a coaxial cable.  The shield terminator includes a solder band and a dam of thermoplastic material which has at least two lumens therein.  One larger lumen receives the coaxial cable while the small lumen receives the ground lead wire.  The presence of the thermoplastic material around both the cable and the lead wire insures that all interstices between the cable, wire and the sleeve of the shield terminator will be filled, preventing the escape of solder from the sleeve, and precluding entry of water and other contaminants into the splice.
Patent CA-2008050-A1 (CA)
Title: Radial shaft seal
Inventor: SCHMITT WOLFGANG
IPC: F16J15/52
Filed: 1990-01-18
Abstract: Abstract In a radial seal for a shaft projecting from a space to be sealed, a seal disk has parallel front and rear faces and is affixed to a reinforcement ring.  The seal disk is made of an elastic deformable material and at its inner edge, is axially drawn in the direction towards its front face, thereby becoming flared to a frustoconical shape, with its rear face slidably engaging the shaft.  The rear face has a helical first groove which encompasses the shaft to provide for retrograde transport of leaking fluid back into the space to be sealed.  The front face has a helical second groove which extends substantially parallel to and coaxially with the first groove and is intermediately positioned to the first groove thereby providing increased surface area for the front face.  This gives better radiation of frictionally produced heat and increases the service life of the seal.

Patent CA-2018239-A1 (CA)
IPC: F02M61/16
Filed: 1990-06-05
Abstract: An injector has a solenoid armature that displaces a valve from its seat to deliver a charge of fuel and air directly into the combustion chamber of a two-stroke cycle internal combustion engine.  When a valve return spring closes the valve against its seat to terminate delivery of the fuel-air charge, the armature separates from the valve stem, and the kinetic energy of the armature is dissipated by a resilient disk or ring.  An adjustment is accessible at the end of the valve stem to establish the valve closing force of the return spring, an adjusting screw establishes the distance between the open and closed positions of the valve, and another adjusting screw positions the resilient disk.

Title: Proportional electropneumatic solenoid-controlled valve
IPC: H01F7/13
Filed: 1990-07-10
Abstract: A rectilinear motion proportional solenoid assembly includes a cylindrical housing containing an electromagnetic coil having a longitudinal coaxial bore. The housing contains magnetic material for providing a flux path for the magnetic field produced by the coil.  A generally cylindrical magnetic pole piece element is inserted  into  the  bore  and  a  movable  armature  assembly  of magnetic material is supported within the bore for movement along the longitudinal axis of the coil by a pair of thin, flexible suspension springs. One of the springs is located within the bore adjacent to one end of the magnetic pole piece whereat an axial gap between the pole piece and the armature is formed. A second spring is located within the housing within the vicinity of a radial air gap between the armature and the housing. The pole piece contains an auxiliary region adjacent to the axial air gap for shunting a portion of the axially directed magnetic flux, for effectively causing the force imparted to the movable armature by the application of a current to the electromagnetic coil to be substantially constant irrespective of the magnitude of the axial gap for a variation in the axial gap over a prescribed range.

Title: Electrogeneration of bromine and use thereof in recovery of precious metals and water treatment
Inventor: DADGAR AHMAD
IPC: C25C1/00
Filed: 1991-08-29
Abstract: A process for generating bromine in an aqueous solution containing bromide ion. An aqueous solution containing bromide ions is caused to flow through an electrogeneration system that comprises paired anode means and cathode means. The system has an inlet and an outlet for the flow of the solution, the solution at the inlet having a pH of between about 0 and about 6 and a bromide ion concentration of between about 0.5 and about 8.8 moles/l. A direct electric potential is applied via the anode and cathode means to cause an electric current to pass through the flowing solution in the electrogeneration system and to generate bromine at the anode means by electrolytic oxidation of bromide ions. The relationship between the electric current and the throughput of the solution through the system is such that between about 4% and about 50% of the bromide in the inlet solution is converted to bromine at the anode means. The pH of the discharged solution is between about 0 and about 6.      The aqueous bromine solution discharged from the electrogeneration system may be used in the recovery of precious metals, such as silver and gold, from sources thereof, and in the commercial and industrial treatment of water.

Filed: 1991-11-08
Abstract: Abstract of the Disclosure A vessel for receiving a test sample of fluid whose water content is to be determined and a thermal neutron sensor are retained in cavities of a biological radioactivity shield. The cavities are lined with a material which blocks external thermal neutrons outside the test sample from being detected by the thermal neutron sensor.  Another cavity, having an inner end terminated by the lining material, receives a source of fast neutrons which are to be emitted through the liner into the test sample to become thermal neutrons if they interact with hydrogen within the test sample.  The latter thermal neutrons which are backscattered to the sensor are detected, and in response an electrical signal encoded to represent the count of detected thermal neutrons is generated to indicate a measure of the water content of the test sample.
